Abstract: Transmissions, transmission lock assemblies, methods of adjusting a gear ratio of a transmission, and methods of forming a transmission shift mechanism are provided. According to one aspect of the invention, a transmission includes a mount assembly including a mount support adapted to couple about a central axle having a central axis, and an eccentric mount defining an eccentric axis and movably coupled with the mount support allowing radial adjustment of the eccentric mount relative to the central axle intermediate a first position and a second position to adjust a gear ratio of the transmission; and wherein resultant forces are generated responsive to the eccentric axis being spaced from the central axis, and the mount support and the eccentric mount are configured to minimize effects of the resultant forces upon the eccentric mount in positions intermediate the first position and the second position.
Abstract: The present invention provides shift mechanisms and methods of controlling a transmission. According to one embodiment of the present invention, a shift mechanism for use with a transmission includes a central axle defining a central axis; a master cylinder configured to increase the pressure of a liquid; and an eccentric assembly comprising a support member provided about the central axle and an eccentric mount coupled with the support member, the eccentric mount defining an eccentric axis and being in fluid communication with the master cylinder and configured to provide radial adjustment of the eccentric axis relative to the central axis providing adjustment of the gear ratio of the transmission.
Abstract: The present invention includes shift mechanisms, lock assemblies and methods of adjusting a gear ratio of a transmission. According to one aspect of the invention, a shift mechanism configured to adjust a transmission includes a central axle defining a central axis; a drive member configured to rotate about the central axle responsive to an application of a driving force to the drive member; and a mount assembly comprising a mount support and an eccentric mount, the mount support being provided about the central axle and the eccentric mount defining an eccentric axis, the eccentric mount being movably coupled with the mount support to provide radial adjustment of the eccentric axis relative to the central axis and wherein resultant forces are generated responsive to the eccentric axis being spaced from the central axis, and the mount assembly being configured to utilize at least one resultant force to assist with movement of the eccentric mount with respect to the mount support.
Abstract: A continuously variable transmission utilizes a variable eccentric assembly arranged about a central transmission axis. A plurality of input and output vanes are operably interconnected to an orbiter and are sequentially engaged by input and output ratchets that circumscribe them. Positive driving connections are provided between the ratchets and vanes by outer toothed pawls yieldably mounted at the outer ends of the respective vanes. A secondary multiplier transmission can be arranged coaxially with the vanes, which are rotatably supported about the central shaft of the transmission.
Abstract: A hybrid transmission provides a continuous range of reduced output speeds in a coaxial relationship about a common central axis within a surrounding cylindrical housing. The input shaft speed is increased through a planetary transmission having a sun gear fixed to a variable eccentric shaft. The eccentric shaft is surrounded by an orbiter and spaced anchor and drive vanes, which are interconnected by a plurality of anchor and drive vanes. Output speed is varied by change of the degree of eccentricity, using a worm gear drive interposed between inner and outer eccentrics within the eccentric shaft. control is achieved through shift rings that rotate a worm in response to external cable tension.
